6oz CO2 tank for Vertical Air?

[Boildown]

Hey all, had a Phantom for a long time (bottom line), but just recently got a 2nd Phantom set up for vertical air.  I have two 3.5oz tanks waiting around for it to warm again in Indiana.  And I just stumbled across this:

A 6oz tank... never knew they had that size.  Anyone have one?  Is this going to be too big for the vertical setup or is it a good tradeoff to get better fills and more shots than the 3.5oz?

Thanks!

It's about the same length as a 7 oz, so it might be a tad bit too long running it vertical, the vertical ASA is attached to the trigger guard, so i wouldn't call it the strongest part on a Phantom. Anything that is heavier and longer than a 3.5 oz might be snap your trigger guard off if you slide into s bunker the wrong way.
